Description
Technical field
The present invention relates to a kind of logging cable, especially a kind of wire armoring photoelectricity is combined logging cable.
Background technology
In recent years, the fast development of photoelectric technology, photoelectricity logging technique is progressively promoted in oil well test field, is believed as light
Number transmission medium optical fiber cable be photoelectricity logging technique key component, and conventional optical cable is generally ordinary optic fibre optical cable, its
Heat resistance and mechanical strength can not meet exploitation high temperature, the requirement of high pressure and deep well measurement condition at present, however, need to solve to survey
The supply of electric power problem of equipment is tried, the construction of cable is tended to be complicated and cumbersome, not only makes outside diameter of cable increase many, more increases electricity
Cable manufacturing cost and use cost, thus its using effect and life-span be affected.
Chinese patent literature CN2497400Y discloses a kind of optical fiber logging cable, is twisted into by optical fiber with copper insulated wire cores
Cable, winding double-layer wire is formed outside extrusion oversheath, and the cable can not meet high temperature requirement, and the construction of cable can not also be met
The requirement of seal request, particularly high pressure and high intensity, optical fiber and core are all easily damaged and influence service life.The patent is produced
Product can not meet the oil well test environment of existing profundity, high temperature, high pressure.
The content of the invention
The technical problems to be solved by the invention are to provide the compound survey of wire armoring photoelectricity that a kind of high temperature photoelectric is integrated
Well cable.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of compound well logging of wire armoring photoelectricity
Cable, high-temperature resistant optical fiber and high temperature resistant filler are placed in the stainless steel tube of center, there is proof copper-wire braided, copper wire outside the stainless steel tube of center
Braiding is extruded by temperature-resistant insulation layer, and high-temperature insulation is placed in outer stainless steel tube, and outer stainless steel tube is armoured internal layer plating
Zinc steel wire and outer layer zinc-coated wire.
The internal layer zinc-coated wire and outer layer zinc-coated wire be different size, it is different twist to high-strength galvanized steel wire.
The high temperature resistant filler is high temperature resistant ointment.
The beneficial effects of the invention are as follows：Cable is to melt optical fiber transmission and supply of electric power in the electricity of the one-line structure of one
Cable, it is compact conformation, succinct, without the other electric power systems of configuration.Ensure that the light of HTHP underground, electric test signal it is same
When transmit；Next ensure that the multiplicating curling of underground optical cable, and work of repeatedly going into the well can be achieved；Due to electrically leading in this cable
The presence in road, the problem that depth is obtained can not be realized by solving conventional optical fiber well logging.
Brief description of the drawings
Fig. 1 is combined the structural representation of logging cable for the wire armoring photoelectricity of the present invention.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description：
As shown in figure 1, the wire armoring photoelectricity of the present invention is combined logging cable, high-temperature resistant optical fiber 1 and high temperature resistant filler 2
It is placed in center stainless steel tube 3, has proof copper-wire braided 4 outside center stainless steel tube 3, proof copper-wire braided 4 is extruded by temperature-resistant insulation layer 5,
Temperature-resistant insulation layer 5 is placed in outer stainless steel tube 6, and outer stainless steel tube 6 is armoured internal layer zinc-coated wire 7 and outer layer zinc-coated wire
8。
The internal layer zinc-coated wire 7 and outer layer zinc-coated wire 8 be different size, it is different twist to high-strength galvanized steel wire.
The high temperature resistant filler 2 is high temperature resistant ointment.
The present invention uses central tubular structure, and center is a stainless steel for being surrounded by filled high-temperature ointment and high-temperature resistant optical fiber
Pipe, tension buffering and resistance hydrogen protection are provided for steel pipe inner fiber.High temperature optical fiber is introduced in welded shaping with the tension force of very little
In stainless steel tube afterwards, and ensure certain length surplus, optical fiber is influenceed with offsetting the steel pipe expansion under the high-temperature condition of underground；
Copper conductor layer is woven outside stainless steel tube, the path of underground electric signal is used as；High intensity is extruded outside the conductor layer woven, it is resistance to
The insulating materials of high temperature；In the stainless steel tube of the certain wall thickness of insulating barrier welding manufacture, resistance to compression protection is provided for downhole cable；Not
Stranded two layers of different size outside rust steel pipe, it is different twist to high-strength galvanized steel wire as armor, two layers of steel wire armor layer is enclosed
Stainless steel tube one stable structure of formation around center, by different forward and reverse stranded balances for causing cable, with
Exempt from lay and use during because moment of torsion is uneven and caused by the rotation of cable play torsion, steel wire armor layer provides for downhole cable
Protection, is crimped, and provide certain tensile strength with the repetition for realizing cable.The cable is to melt optical fiber transmission and electric signal biography
The cable of the defeated one-line structure in one, repeatable curling uses, compact conformation, succinct, without the other power supply systems of configuration
System, meets the normal work in the case of 300 DEG C of well temperature.The cable be light, electric logging technology large-scale promotion application there is provided
Reliable technical guarantee.
In summary, present disclosure is not limited in the above embodiments, and the knowledgeable people in same area can
Can propose other embodiments easily within the technological guidance's thought of the present invention, but this embodiment is included in this hair
Within the scope of bright.
